Today I lost some hash rate while the miner was connected to the US public URL. The miner was running at 180 GH/s but the reported hash rate dropped to 120 GH/s. It wasn't turning into stales or rejected shares - the hashes just simply disappeared. I noticed some new type of load balancing going on with the public URL. Could this have something to do with it?
In any case, I connected the miner to my assigned private IP and used a semi-private address as the backup pool and the problem went away.

Not much to look at, but pulls a steady 450Ghs overclocked. Within the sea of fans is a bitfury m-board with 12 h-cards plugged in. Disclamer: the images contain a shameless attempt of marketing somewhat unrelated goods.   Behind the rig is an open window, the ups cardboard is in place to prevent direct rainfall on the rig should winds blow in the exactly right direction at massive force. How come some H-cards appear to have custom heat sinks and some don't? |

How far along is shipping for October deliveries? Is there a thread here tracking them? What order number are they up to?
I believe there are 2 order queues: one for old H-boards and another for everything else. The old H-boards queue has started moving last week but has not yet reached mine (#8xx). |

Avalon has actually started being quite reliable lately, seems they shipped out the tradehill auctions within just a few days and if you order what they currently have in stock in the store it should be the same speedy shipping.
Yep, a few days ago I bought an Avalon Mini for 6 BTC direct from the Avalon store. Today my miner is already sitting at the DHL Cincinnati hub awaiting customs clearance. Not sure if I can make back the 6 BTC through mining, but I thought I'd give them another chance since I'd made a fortune from my B1 Avalons. |

I have two stubborn version 1 M boards, that just wont hash properly with more than 3 H cards.
I get 115GH/s with 3 H-boards. The moment I add the fourth it falls to 84GH/s with lots of errors (not MISO not SPI, but hashing errors).
Using stock software, tried both Autotune on and off. I guess I will have to dig deeper. Hashrate starts off good after power-on and falls down within a minute or so.
Anyone faced this conundrum?
If your H cards are super over-volted (over 0.8 V), try reducing the voltage a little. I'd read your earlier posts about those 40 GH/s mods and there was no way I could reproduce them on a 16 card v1 M board. It worked fine for a few cards but for a full rack 30 GH/s per card seemed to be the highest stable rate I could get. |

Be cautioned however .....the guy I talked to said stuff would arrive from Brussels tomorrow to the Midwest usa where I live....I really am not sure either about this in hindsight
perhaps they don't have a clue about the country....(ie how large usa is) anyway.....it was a 'real person" and they said they looked it up..all I have to go on ..but how good their timeline really is i'll guess we will see on Friday...nice enough fellow thou
Depends how far in the Midwest you are from DHL's Cincinnati hub, from where the stuff will probably land. |

Dave, I currently have a V1 Starter with a 2nd H board. I have an order for an October Starter and 6 individual orders for 1 H board each. In a situation like that, what and when will you ship?
Since V1 H boards are shipping earlier, would it be possible to ship me a few V1 H boards? And then send me the remaining V2 boards along with the V3 Starter?
I am in the same situation. I emailed Kat which of my orders needed to be filled with old H boards and she acknowledged within a day. |

Finally got it all set up nice and pretty. Currently pulling 16A @ 240V  showoff..  Looks nice.  20K cost if you bought in at old prices??? When did you have your units delivered (I'm envy to see if you made ROI unlike me ) If they were FPGA trade-ins break-even ROI in USD might have been reached long before they were delivered. |

I have a Corsair AX860 waiting for my Mercury. It's made by Flextronics so I'll feel safe using it.
I have always thought that the AX860 was made by Seasonic and the AX860i by Flextronics. |

Maybe I'm an optimist. But I'm not buying any ASIC until I know it can earn me more than I can make just buying BTC.
You can't possibly expect to make a profit while taking on zero risk. If that were the case you'd forever be in the sidelines. Mining profits are dependent on future difficulty which nobody can predict with any certainty. Mining for profit will always involve some level of risk. |

I think people like to drop the phrase "My pi" in casual conversation. It places them a notch above the Apple store guru. An RPi + 4 Eruptors also costs much less than a new iPhone, so it is not really a waste of money in the grand scheme of things.

1. I want to replace the 650W PSU with an 850W PSU, I wonder if someone could recommend one I could buy today to replace it?
The Corsair AX860i is probably one of the best 850W PSUs that can fit into a Batch 1 Avalon without any modifications. |

what was the price in BTC?
BTC was really low. An Aug kit ran roughly 225-250 BTC. They will unlikely break even in BTC. BTC was around $80 when I placed my order, so it worked out to 240 BTC for me. I am actually systematically cashing out of BTC, so my motives for buying do not take into consideration ROI optimization. |

out of curiosity, how much has been mined so far by those that got starter kits or full august kits
Till today, I've mined little over 31 BTC from a full August kit that arrived on Sep 5. This is just an estimate based on a percentage of my total hash rate on BTC Guild. |

Hello,
Got an Avalon Clone with 4 modules today. I'm using a Coirsair HX1050 psu.
I turn on the machine, wait a bit, plug a lan cable and nothing happens. On my computer it shows the connection as cable not plugged in.
I've connected directly to my computer (192.168.0.101).
What am I missing?
Crossover cable should be used for direct connection. I am pretty sure the WR703N has Auto-MDIX. Any cable (straight or cross) should be fine. |

got over 100-200 btc a day for a few months
As others have pointed out, this is nonsense. At January first 2013— long before any avalon miners existed regardless of what Chinese conspiracy theories you have— difficulty was 2979636. At 60GH/s this would have resulted in 10.13 BTC/day, an order of magnitude higher than you claim. By the time any were reported in anyone's hands anywhere the difficulty was 2968775 ... very slightly _lower_, which is again evidence that no one was turning on some big mystery asic farms at the time. This bit of complete nonsense degrades what is otherwise an OK post, you ought to fix it. Indeed, the only time an Avalon could have made 100-200 BTC a day was back in June 2011 or earlier. |

You can 'overclock' them with the pencil mod but you cannot do it on a full rig if I am not mistaken.
You can do full rig but you need some thing to cool down boards or put heatsink on each board. I thought that was too much power for the regulator to handle. Definitely agree about upping the cooling. I've done it on a full rig, albeit moderately to about 440 GH/s. The regulator and 30A fuse are on each individual H-card. |

Here is my V1. Looking forward to the V2    Any update on the version that can fit in a standard 19-inch rack? I'd be interested in those.
With the current version 2 of these can stand sideways vertically using 13U or 14U of height, but there will be is a lot of wasted space.
I'm working on it. Do you require it to be fully enclosed, or is this open design ok? I forgot I had asked this question a while back. Anyway, open air is fine for me. |
